Hydrodynamic Analysis of the New Type Energy Capture Device

摘要

Buoys traditional uses battery for energy supplement, which may have shortcomings, such as short working life, inconvenient battery replacement, etc. Therefore, renewable energy analysis becomes a hot topic. In this regard, this research proposed an energy capture device located in the buoy. It collects the kinetic energy of the buoy and stores it in an accumulator when the buoy floats on the sea surface. The hydrodynamic characteristics of the device under the fourth-order sea conditions are study by using CFD numerical simulation. It is evident that the proposed device has energy capture function.
